“…We hypothesized that CI users may perceive music to be equivalent to noise, and thus, participants may be applying the same cognitive processes of recognizing speech in competing backgrounds to processing song lyrics within a song. These findings were consistent with a near‐infrared spectroscopy study comparing lyrics and melody song processing among normal hearing 4.5‐month‐old infants with 12‐month‐old infants 26 . In this study, 4.5‐month‐old infants demonstrated right hemispheric activity when lyrics were modified, when the melody was modified, and when both the lyrics and melody were both modified.…”

Objective To evaluate the impact of vocal boost manipulations on cochlear implant (CI) musical sound quality appraisals. Methods An anonymous, online study was distributed to 33 CI users. Participants listened to auditory tokens and assessed the musical quality of acoustic stimuli with vocal boosting and attenuation using a validated sound quality rating scale. Four versions of real‐world musical stimuli were created: a version with +9 dB vocal boost, a version with −9 dB vocal attenuation, a composite stimulus containing a 1,000 Hz low‐pass filter and white noise (“anchor”), and an unaltered version (“hidden reference”). Subjects listened to all four versions and provided ratings based on a 100‐point scale that reflected the perceived sound quality difference of the music clip relative to the reference excerpt. Results Vocal boost increased musical sound quality ratings relative to the reference clip (11.7; 95% CI, 1.62–21.8, p = 0.016) and vocal attenuation decreased musical sound quality ratings relative to the reference clip (28.5; 95% CI, 18.64–38.44, p < 0.001). When comparing the non‐musical training group and musical training group, there was a significant difference in musical sound quality rating scores for the vocal boost condition (21.2; 95% CI: 1.76–40.7, p = 0.028). Conclusions CI‐mediated musical sound quality appraisals are impacted by vocal boost and attenuation. Musically trained CI users to report greater musical sound quality enhancement with a vocal boost with respect to CI users with no musical training background. Implementation of front‐end vocal boost manipulations in music may improve sound quality and music appreciation among CI users.

“…During the typical development of social auditory and language information processing, infants and children exhibit increased sensitivity to stimuli that carry greater social and language values (61, 62). They also switched from recruiting bilateral auditory circuits to a linguistic circuit that is more left hemisphere dominant (61, [63][64][65][66][67]. Although some studies failed to find age-related differences during their targeted age range (Zimmermann et 11-month-old infants but greater temporal lobe activation when processing pseudowords that varied in linguistic characteristic than in vowel duration in infants aged 13 to 28 months old (61).…”

Understanding the neurodevelopmental trajectories of infants and children is essential for the early identification of neurodevelopmental disorders, elucidating the neural mechanisms underlying the disorders, and predicting developmental outcomes. Functional Near-Infrared Spectroscopy (fNIRS) is an infant-friendly neuroimaging tool that enables the monitoring of cerebral hemodynamic responses from the neonatal period. Due to its advantages, fNIRS is a promising tool for studying neurodevelopmental trajectories. Although many researchers have used fNIRS to study neural development in infants/children and have reported important findings, there is a lack of synthesized evidence for using fNIRS to track neurodevelopmental trajectories in infants and children. The current systematic review summarized 84 original fNIRS studies and showed a general trend of age-related increase in network integration and segregation, interhemispheric connectivity, leftward asymmetry, and differences in phase oscillation during resting-state. Moreover, typically developing infants and children showed a developmental trend of more localized and differentiated activation when processing visual, auditory, and tactile information, suggesting more mature and specialized sensory networks. Later in life, children switched from recruiting bilateral auditory to a left-lateralized language circuit when processing social auditory and language information and showed increased prefrontal activation during executive functioning tasks. The developmental trajectories are different in children with developmental disorders, with infants at risk for autism spectrum disorder showing initial overconnectivity followed by underconnectivity during resting-state; and children with attention-deficit/hyperactivity disorders showing lower prefrontal cortex activation during executive functioning tasks compared to their typically developing peers throughout childhood. The current systematic review supports the use of fNIRS in tracking the neurodevelopmental trajectories in children. More longitudinal studies are needed to validate the neurodevelopmental trajectories and explore the use of these neurobiomarkers for the early identification of developmental disorders and in tracking the effects of interventions.
